Function
Important transcription factor regulating the expression of genes involved in immune and inflammatory responses (PubMed:16585579, PubMed:17911624, PubMed:18486321, PubMed:20111005). Plays also a significant role in adipogenesis, as well as in the gluconeogenic pathway, liver regeneration, and hematopoiesis (PubMed:9727068, PubMed:10635333, PubMed:17301242, PubMed:17601773, PubMed:19478079, PubMed:24061474, PubMed:24216764). The consensus recognition site is 5'-T[TG]NNGNAA[TG]-3'. Its functional capacity is governed by protein interactions and post-translational protein modifications. During early embryogenesis, plays essential and redundant functions with CEBPA (PubMed:15509779). Has a promitotic effect on many cell types such as hepatocytes and adipocytes but has an antiproliferative effect on T-cells by repressing MYC expression, facilitating differentiation along the T-helper 2 lineage (PubMed:9727068, PubMed:10635333, PubMed:16585579). Binds to regulatory regions of several acute-phase and cytokines genes and plays a role in the regulation of acute-phase reaction and inflammation. Plays also a role in intracellular bacteria killing (PubMed:17911624). During adipogenesis, is rapidly expressed and, after activation by phosphorylation, induces CEBPA and PPARG, which turn on the series of adipocyte genes that give rise to the adipocyte phenotype. The delayed transactivation of the CEBPA and PPARG genes by CEBPB appears necessary to allow mitotic clonal expansion and thereby progression of terminal differentiation (PubMed:15985551, PubMed:17301242, PubMed:17601773, PubMed:20194620). Essential for female reproduction because of a critical role in ovarian follicle development (PubMed:9303532). Restricts osteoclastogenesis (PubMed:19440205). UniProt

Subunit Structure
Binds DNA as a homodimer and as a heterodimer. Interacts with ATF4. Binds DNA as a heterodimer with ATF4 (PubMed:11018027). Interacts with MYB; within the complex, MYB and CEBPB bind to different promoter regions (PubMed:11792321). Can form stable heterodimers with CEBPA, CEBPD and CEBPE (By similarity). Isoform 2 and isoform 3 also form heterodimers (By similarity). Interacts with TRIM28 and PTGES2 (PubMed:9742105, PubMed:15879117). Interacts with PRDM16 (PubMed:19641492). Interacts with CCDC85B (PubMed:15644333). Forms a complex with THOC5 (PubMed:19015024). Interacts with ZNF638; this interaction increases transcriptional activation (PubMed:21602272). Interacts with CIDEA and CIDEC (PubMed:22245780). Interaction with CIDEA increases transcriptional activation of a subset of CEBPB downstream target genes, including ID2, IGF1, PRLR, SOCS1, SOCS3, XDH. Interaction with CIDEC increases transcriptional activation of SOCS1, SOCS3, TGFB1, TGFBR1, ID2 and XDH. Interacts with DDIT3/CHOP. Interacts with EP300; recruits EP300 to chromatin. Interacts with RORA; the interaction disrupts interaction with EP300 (PubMed:19324970). Interacts (not methylated) with MED23, MED26, SMARCA2, SMARCB1 and SMARCC1 (PubMed:20111005). Interacts with KAT2A and KAT2B (PubMed:17301242). Interacts with ATF5; EP300 is required for ATF5 and CEBPB interaction and DNA binding (PubMed:24216764). UniProt

Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB

Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
